' 'This invention relatesito anchoring members, and more particularly to means fork anchoring. pipes and the like. f

v.One ofthe objects of theinvention is th provision of ,new andimproved means for clamping` pipes and the like and holding them in 'asdefinite yfixed position.`

*.Anotherfobjectof the invention is lthe provision -ofiiew and improved clamping means :on pipe vanchorswhereby pipes and' the like may be secured in position and the Aclamping member permanently andeflicientlylocked inl clamping position.

Astillfurther job' ct of the invention is v and a clamping member insertable in either.v

the provision o f a new and-improved pipeanchor having a pluralityf'of camy surfaces direction throughsaid anchor and'having an arm `adapted tobe bent over oneitherfofsaid surfaces for holding theparts in clamping position? v j Other and further objects andadvantages of the invention willfappear from-thefollowing description taken in connection with the accompanying drawings, in which:

,Air pipes and the like usedl yon railway carshave a tendency to creep or move lonf gitudinally along the can due tothe sud-l den stopping ork starting of thefcars and the inertia of the pipes. While the present` invention is especially adapted to retain pipes in or under carsrigidly in position vunder these conditions, it is understood that the device is equallyas useful for supporting and anchoring pipes andthe like,` in

otherv relations and Aunder other conditions.y

Referring now to the drawings, the reference numeral 10 designates a support which may be` a cross member beneath a railway car, through which the pipe 11 extendsl The pipe 11 may be the mainair pipe or conduit throughwhicli air under compression `is delivered to the auxiliary air tanks beneath the car, astis usual inV such constructions.

An anchor member 12 is provided for holding .the pipe 10 in fixed position. In the x form of thedevice selectedto illustrate one embodiment of the invention, the anchorV member 12 comprises a body portion 13 Y provided with a slot or recess 14 for'receivipe'11.` The lowery marginal or-i` ing vthe tion v of t e recess maybe and preferab y is provided with converging inclined surfaces forming a seat 15 against which-the pipe 11` is'a'dapted to be clamped or wedged.` One or bothof the side members forming the slot or recess are'extended to form anarm or arms i 16 having inclined orcamming. surfaces 17;

The bodyportionof the' anchoring member is also' provided with' 'anl attaching. iiange orv ears;18 through which fastening means such as Athe-rivets' 19.- are adapted `to extend for securing'the 'fmembers tog' the support 10.-

Suitable means `are provided for` clamping the pipeagainstthe'seat 15. As shown, the

" arms-16 are vprovided.withaline'd keyholey Slots/121,'k see-Fig. 3,.inwhi`ch is adapted to be `inserted a A.key `or clamping member 22. The key or clamping' member 22has an eccentric Vclamping .lug 23 lfor engaging the pipe 11 and one end is provdedwitha laterally extending lug 24 forming with the end a key-shaped member vfor engaging the keyy hole kslot` 21in.either` of the members 16.

The opposite end ofthe clamping member 22 is provided with a projection or arm 25 forming Aa handlel for rotating `the key or clamping member 22 afterl the same has been inserted through the openings21.

In certain uses of the device; as Ontrains that. the "clampingl-member be turned suific ciently to .verytghtly grip the pipeto pre-` vent the inertia of the samef-rom. causing" it to creep along'- the body on which it is mounted, on suddenly starting or stopping the same. For this 'purpose thearm 25 is of sufficient length that itmay be bent over and forced downwardialong the inclined surface 17. In practice, theA anchor memberis secured in position withfthe pipepseated in the recess', the `clamping member is inserted, I

outer end ofthe arm 25 is bent `over and cannot be inserted from one side.

driven downward along the inclined surface 17 by means of a hammer, thus very firmly clamping the pipe against the converging surfaces 15. Since the surfaces are sub-- stantially tangent to the curve of the pipe, and are arranged to converge downwardly, the clamping member forces the pipe into the 'angle thus formed whereby an exceedingly eflicient clamping action is obtained.

ln some instances, the anchor member will be so located that the clamping member 22 In this event it may be inserted from the lopposite side and on turning the saine will be locked in position, the keyhole slot in each side being provided for this purpose. rlhe anchor member is also preferably provided with the two arms 1G for the same reason. lt is understood that only one of these arms is necessary, but by providing the two arms the necessity for manufacturing them in rights and lefts is obviated, and the device is adapted for universal use.

lt is thought from the foregoing talren in connection with the accompanying drawings that the construction and operation of my device will be apparentto those skilled in the art, and that various changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims. A v y I claim as my invention:

1. A combined pipe hanger and clamp comprising a body portion, arms extending upwardly from said body portion, said arms being 'provided with alined openingsone of which is in the form of a key-hole slot, a key having a laterally extending lug for engaging said openings, a pipe-engaging lateral extension on said 1re and means for holding said key in adjusted angular position within said openings. l

2. A. pipe hanger, comprising a body portion provided with perforated ears and having arms forming a seat for a pipe, one of said arms being provided with an inclined surface,V a clamping member rotatably mounted in said arms, and means on vsaid member for engaging said inclined surface for holding said clamping member inr adjusted position.

a seat for thereception of a pipe, a rotating n member for clamping said vpipe in said seat,

a member having an inclined surface, on

said body portion, and an arm on said rotating member for turning the same, said arm being adapted to be bent over and along saidinclined surface for holding said rotating member in clamping position.

5. A pipe anchor comprising a member liavinga pipe seat therein, and a cooperating inclined cam surface, a rotatable clampA ingelement for clamping a pipe in said seat, and cam surf-ace engaging means on said element for forcing said element into clamping engagement with a pipe in said seat.

6. A combined pipe hanger and clamp comprising a body portion, arms extending upwardly in spaced relation from said body portion to form a seat for a pipe, alined openings in said arms, a key rotatably mounted in said openings and provided with lateral extension for clamping said pipe in said seat, and means for holding said hey inv adjusted pipe clamping position on said arms.

,7. A pipe anchor member comprising a body portion having a recess forming a seat for a pipe, arms having inclined surfaces rigidly secured to said body portion, said arms being provided with alined apertures, a clamping member insertable in either direction through saidapertures, and a projection on said member for turning the same to clamp a pipe in said seat, said projection being adapted to be bent over an adjacent inclined surface on said arms.

In testimony whereofl aiiix my signature.
